Proven Results

Black & Veatch is proud of its relationships with several mining companies, such as Newmont, Rio Tinto, BHP, Goldcorp, Anglo American, Kinross and many more.

BREWER GOLD MINE, JEFFERSON, SC

The Brewer Gold Mine, located near Jefferson, South Carolina, operated intermittently between 1828 and 1995. After the site was abandoned in 1999, the U.S. Environmental Protection Agency (EPA) took over the site’s water treatment operations to contain acid rock drainage that could harm Little Fork Creek and the Lynches River. In 2005, the EPA placed the site on the Superfund program’s National Priorities List (NPL) and selected Black & Veatch to perform remedial investigations and feasibility studies to protect surface water. Work also included reviewing and streamlining operating procedures for the existing water treatment plant, which reduced costs without decreasing operating efficiency.

MINING CLIENT, AK

Black & Veatch provided a fuel supply study, “island” power distribution and a cold weather / remote man camp construction execution plan. Other work included engineering design, risk assessment and financial evaluation.

ELECTRICITY PURCHASE SUPPORT FOR LARGE MINING CUSTOMER, USA

Black & Veatch continues to provide support to a large mining customer in the United States to implement new electricity supply agreement. This support includes analysis of agreement structure, identification of data to validate invoicing, analysis of electricity procurement options available under the agreement including analysis of day ahead versus forward purchasing, development of electricity price forecasts, development of electricity demand forecasts and statistical analysis of forecast electricity budgets.

“Just like the current dam is a strong foundation for our future work, Black & Veatch’s resources and expertise will build on our existing project management team and will

contribute significantly to delivering a successful project for Denver Water’s customers.”

JEFF MARTIN | PROGRAM MANAGER FOR THE GROSS RESERVOIR EXPANSION PROJECT.

GROSS RESERVOIR EXPANSION PROJECT, DENVER, CO

As Owner’s Representative, Black & Veatch will assist Denver Water with project controls – including schedule, cost and document control, and eventually construction management – starting in May 2017 and extending through the first filling of the reservoir, expected in April 2026. Once permits are secured, dam construction is expected to occur in three phases over a total of four to five years. The project will raise the height of the existing 340-foot-dam by 131 feet, increasing reservoir capacity from 42,000 acre feet of water to 119,000 acre feet of water. The project will also increase the total output of Gross Dam’s hydroelectric power plant from 7.6 megawatts (MW) to 8.1 MW.●● The project, with an estimated cost of $380 million, will make Gross Dam the tallest dam in Colorado and will increase the dam to 1.5 million cubic yards of concrete, about half the volume of Hoover Dam.

●● The expansion will also provide environmental benefits, with agreements in place to protect the South Boulder Creek and the Fraser, Williams Fork, Blue and Colorado rivers.

GEOTECHNICAL EVALUATION MAJOR DAM, CANADA

Black & Veatch participated in an investment level geotechnical evaluation for the design of a major dam for a mining client in the Arctic region of Canada. The dam was located in a permafrost region, with a likelihood that the permafrost would melt once the structure was filled. This was a particularly challenging project, especially given the harsh climatic and challenging geotechnical conditions encountered in the region. The dam was a critical component of the project, and required the high level of expertise that Black & Veatch could bring to the project.
